What is a planning or building regulations application?

Planning permission decides whether a project can be built; building regulations decide how it must be built. Most extensions, lofts and conversions need building regulations approval even when planning permission is not required.

Planning and building regulations in Leighton Buzzard
Approvals for a planning or building regulations application in Leighton Buzzard follow the rules for England. In England householder applications, lawful development certificates and prior approvals for larger home extensions go to the local planning authority. Building control can be the council or a registered building control approver.
Where work involves a shared wall, building on the boundary, or digging foundations within 3 metres of a neighbour’s building and deeper than its foundations (or within 6 metres for deeper work), the Party Wall etc. Act 1996 applies and notices must be served before work starts.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.

What happens if I build without approval?
The council can take enforcement action, and missing approvals cause problems when selling. It is always better to get approvals first.
Who carries out building control?
Either the council’s building control service or, in England and Wales, a private building control body registered to do the work. In Scotland and Northern Ireland building control is provided by the council.
What is a lawful development certificate?
A certificate from the council confirming that a project is permitted development. It is optional but useful when selling the house.
